DE motor? What rpm did you set your limiter to? What valve springs and cams?

 

Yes, DE Rev Up motor with stock cams and Supertech valves, 1mm bigger intake and exhaust then stock.

 

What EMS are you using, VEMS perhaps?

 

I am using this:

Sorry, but it is a Hungarian site. What parameter do you need?

 

You can find pinout for ECU and all other things in the Factory Service Manual (FSM). Look online for the model/year of vehicle your ECU came from.

I've never heard of over-advancing intake valves on stock ECU or popular VQ management systems. But if you're using some other kind of ECU with different voltage or frequency parameters, maybe it can happen. Why not go with something proven with VQ's like Haltech? Or maybe stock ECU with Uprev tuning?

 

Thanks!

Why I use this? Because when I started this project, then I didn't know about Haltech and my ECU is a great one. But this problem opened my eyes and I don't want to crash my engine. I am thinking of the Haltech but it cost me lot and lots of work again with the electronic system.

So you didn't hear about it still now. I think it can happened...

 

BMW M3 S50B32

 

Very nice pictures. The combination of oversize valves in conjunction with extra lift might pose a problem - it certainly appears to on that M3 engine.

On a vq35de with stock cams, I cannot imagine this would be an issue. With high lift cams, I think you would definitely have to be careful about maximum lift during overlap as the cams are probably not designed with oversized valves in mind.

 

Stock ECU probably cheapest option (with Uprev flash to shut off NATS and remap fuel) if you want to run it this way, at least in the beginning.

 

I am thinking on the Haltech or Syvecs. It depends on that, how can I model camshaft advancing problem with my ECU.

New project

Lada TT project still running. I don't have much photos, but it started after 2 years!

 

Is that a BMW e30?

 

Yep.


I'm interested in how this will turn out

 

Oh, I don't need anything particular, was just curious since VEMS is developed in Hungary and lot's of project cars there are powered with it.

Good luck with E30 and VQ35HR, that will be awesome car no doubt .

 

Vq35 in e30? Yes!!

 

Sub'd. This looks like some damn fun.

 

Thank you guys! Yes, it is an E30. My plan is to use the OEM ECU and looks like an original E30. But it is not so easy than I thought when I started this project. But I don't know what is impossible mean.

 

Keep some updates coming, I love watching your stuff

 

That is one sweet looking E30 project!

 

good to see that some guys stop using 2Jz for a swap
